Sheffield Knife Set

[color=darkblue]I have a set of 6 silver Sheffield knives that are boxed. The top edge of the knife is serrated. Each knife measures 6 and 1/2" long and has what looks to be an ivory handle. The handle is attached to the blade with a silver band. The blade says “Sheffield” and has a crown with an “A” inside. On the left of the crown is the letter “E” and on the right, the letter “P”. I would like to know what the knives are used for, their approximate date and value. Please see photo. Thanks so much!
